The V8 inspector is using the DebugPropertyIterator (a debug only
interface) while building RemoteObjects. The DebugPropertyIterator
uses the `KeyAccumulator::GetKeys` for this, which can potentially
throw, but the DebugPropertyIterator ignores exceptions and keeps
iterating. If multiple iteration steps throw an exception
(e.g. due to a pending stack overflow), we run into a CHECK in
Isolate::Throw, as we can't throw exceptions while another
exception is still pending.
This CL fixes the CHECK crash by properly propagating exceptions
after the iterator is created or advanced and returning early
in the inspector if an exception happens.
Please note that the regression test that showcases this behavior
is still disabled, as fixing the crash causes currently an
endless loop. While the exception in `ValueMirror::getProperties`
is handled by early returing, we still need to forward it as
the result of the `Runtime::evaluate` all the way up the stack.

The write barrier for storing a reference to an object requires the
destination offset as a parameter. The existing code only passed the
immediate offset, however, not the offset provided through a register.
With this CL, the correct offset is provided.

DevTools can't unambiguously determine whether code is JS or wasm.
This CL adds a string to the tracing output that will be 'JS', 'wasm' or
'other'.

While clang++ doesn't mind, g++ complains about apostrophes in #error
messages as they appear to be unterminated single-quoted literals. So
add surrounding double-quotes.

The inlining of JS-to-Wasm wrappers can fail inside try/catch because
the IR built by WasmWrapperGraphBuilder::BuildJSToWasmWrapper does not
always set the correct control outputs in the call node.
This patch disables inlining inside try/catch to work around this issue.

The bytecode offset (previously 'bailout id') was referred to as 'ast
id', 'node id', 'bailout id' in different spots. And 'bailout id' was
used to refer to deoptimization exits. This CL makes used terms more
consistent.
